**10th Grade Pre-Calc**

The demand equation for a hand-held electronic organizer is... P=5000(1-(4/4+e^-.002x)) Find the demand x for a price of (a) P=600? So strange. Thx for help
*Tuesday, January 17, 2012 at 12:02am by Anthony Clay*

**10th Grade Pre-Calc**

Don't you mean P = 5000[1 - 4/(4 + e^-.002x)] ? If P = 600 , 0.120 = [1 - 4/(4 + e^-.002x)] 4/(4 + e^-.002x)] = 0.88 4 + e^-.002x = 4.5454 e^-.002x = 0.5454 -0.002x = ln(0.5454) = -0.6061 x = 303
